Abstract: The invention relates to highly reactive reagents and compositions for the purification of waste gases and flue gases and for effluent treatment, and to processes for the preparation and to the use thereof. The reagents and compositions represent mixtures of calcium hydroxide with additives, in particular clays, rock powders, carbonaceous products such as pulverised coal and fly ashes and, if appropriate, waterglass, which are porous due to their special preparation and have a large specific surface area of up to about 200 m<2>/g. Using these sorbents, it is possible, in addition to heavy metals, it is also possible in particular to separate hydrocarbons and halogenated hydrocarbons, dioxins and furans from waste gases and effluents. Further advantages are the easy hardenability of the resulting products and their high degree of safety in landfills.

Abstract: A glass melting furnace having a firing chamber, having at least one nozzle for supplying fuel into the firing chamber, having at least one channel (20, 14) separate therefrom for supplying air into the firing chamber, and having at least one aperture (27-29, 35-37) arranged downstream of the nozzle and connected to a feed source (21) for essentially pure oxygen (22-26, 30-34), in order to effect stepwise firing in this way. When pure oxygen is fed in, a smaller amount is necessary than when air is fed in. Although the pure oxygen can be fed in in cold form, it does not cause any significant cooling in the firing chamber in the feed region. Gas jet pumps and hot air lines of large cross section which need to be insulated are unnecessary. The costs of the process are reduced. <IMAGE>

IPC: H04N5/208
Filed: 1991-11-07
Abstract: This invention relates to a picture quality improving circuit for automatically obtaining an optimum image by catching the features of input video signals. The invention first compares an input luminance signal with a plurality of reference values, measures the results of comparison by a plurality of counters (12, 14) and obtains cumulative histograms within a predetermined period of time. Next, the cumulative histogram signals are stored in a latch circuit (32) for a predetermined period of time, and an interpolation circuit determines and outputs a correction signal corresponding to the input luminance signal by interpolating the cumulative histogram signal. When a large number of dark signals exist in the input luminance signals, the cumulative histogram signals describe an upwardly projecting graph and a dark portion is extended in a bright direction. In this way, picture quality can be improved.

Title: Voltage-boosted phase oscillator for driving a voltage multiplier
Inventor: PASCUCCI LUIGI
IPC: H03K3/354
Filed: 1991-02-07
Abstract: A voltage-boosted phase oscillator for driving a voltage multiplier comprises two intermeshed ring oscillators, each composed by an odd number of inverters connected in cascade through a closed loop and generating a normal phase and a voltage-boosted phase derived from the normal phase through a bootstrap circuit. The frequency of oscillation of both intermeshed ring oscillators is established by means of two similar RC networks common to both loops. The synchronization of the respective oscillations of the two rings is ensured by means of a plurality of SR flip-flops connected in cascade, formed by two NAND gates which, singularly, constitute as many inverters of the two rings. The oscillation and the arresting of the oscillation are controlled by means of a logic signal fed to a common input of a first pair of NAND gates which constitute respectively a first inverter of the relative ring oscillator and to a second input of which the phase produced by the relative ring oscillator is fed.

Abstract: Système servant à amener de l'oxygène à un oxygénateur à membrane perméable aux gaz. Le système peut comprendre une source intégrée (10) de gaz sous pression et une source de vide (12). Un premier régulateur (106) de flux massique est relié à la source de gaz (10) en amont du dispostiif échangeur de gaz (14) dans le flux gazeux. Une soupape de compression (112) est placée dans le flux gazeux entre ledit premier régulateur (106) et le dispositif échangeur de gaz (14). Un évent atmosphérique (110) est placé entre la soupape de compression (112) et ledit premier régulateur (106). Un second régulateur (128) de flux massique est placé en aval du dispositif échangeur de gaz (14) et est relié à la source de vide (12). Un contrôleur central (130) commande la soupape de compression de manière à maintenir une pression subatmosphérique à l'entrée du dispositif échangeur de gaz (14). Ledit second régulateur (128) est commandé de sorte qu'il maintienne un débit voulu à travers ledit échangeur (14), tandis que le premier (106) est commandé de sorte qu'il maintienne un débit plus élevé que celui du second régulateur (128), afin d'assurer un débit suffisant de gaz à travers la soupape de compression (112) et le dispositif échangeur de gaz (14). Le gaz excédentaire est évacué par l'intermédiarie de l'évent (110). On peut ainsi assurer un débit suffisant de gaz dans le dispositif échangeur de gaz (14) pour permettre un échange de gaz avec le sang, la pression du gaz dans ledit échangeur (14) étant suffisamment basse pour empêcher un quelconque dégazage par formation de bulles dans le sang.

Abstract: The apparatus according to the invention for guiding a laser beam avoids tilting the laser beam with regard to the exposed plane by the laser beam being displaced parallel to a perpendicular direction of incidence. A support roller with a spiral band on the circumferential surface serves as deflection element. The band has a reflecting surface. A laser beam running parallel to the circumferential surface strikes the reflecting surface and is reflected towards the exposed plane. The striking point shifts on the reflecting surface of the band through rotation of the support roller so that the laser beam is displaced in parallel. The reflecting surface can be of hollow-mirror-like and slanting design. <IMAGE>
